摘要
[目的]探讨极小种群野生植物海南假韶子在三亚的分布现状与生境调查.[方法]采用实地调查方法,对极小种群海南假韶子野生种群的植株进行调查.[结果]海南假韶子集中零星分布于落笔洞和亚龙湾热带天堂森林公园,估植株成熟个体数低于100株,在水平分布上不连续,呈聚集分布,分布较为狭窄.以种子萌发和气生根根萌的方式繁殖,但林下幼苗数量较少,幼苗自然更新不良,种群生境人为干扰严重.[结论]生境的破碎化与海南假韶子自身的生物学和生态学特性是影响种群更新的重要因素.
[ Objective]The aim was to study the habitat and wild population distribution of Paranephelium hainanensis species with extremely small populations in Sanya City. [ Method] The distribution of P. hainanensis species was investigated by field investigation. [ Result] P. hain-anensis concentrated distribution in Luobidong and Yalong Bay Tropical Paradise Forest Park, with a total population of less than 100 mature individuals. In the horizontal direction, the distribution of P. hainanensis in Sanya was discontinuous, aggregated distribution and narrow. The spread by seed germination and root-sprouting, but was no seedlings under the forest. The natural regeneration of P. hainanensis was difficult , which the habitat was disturbed seriously human destruction. [ Conclusion ] Habitat fragmentation and biological and ecological characteristics of P. hainanensis were important factors for population regeneration.
